The oldest lunar features are called lunar highlands. These are areas on the Moon's surface that are heavily cratered and have not experienced significant volcanic activity, making them some of the oldest regions on the Moon.

The youngest lunar feature is a volcanic crater called Aristarchus Plateau located on the Moon's near side. It has a bright spot due to recent volcanic activity, and radiometric dating estimates its age at around 450 million years old.

Some of the oldest lunar features include the highland crusts in the southern hemisphere of the Moon and impact craters like the South Pole-Aitken basin. These features provide valuable insights into the early history of the Moon and the solar system.

Form factor represents the feature placement, size and general layout in a mother board. The AT form factor is considered to be the largest and the oldest.
The Earth has lots of tectonic activity, by which I mean earthquakes and volcanoes, which the moon does not have. Rocks can survive longer on the moon.
The oldest known calendars are lunar based, and the oldest of these discovered thus far comes from the Aurignacian culture, a Paleolithic society that existed in central and southern Europe and southern Asia. Aurignacian culture existed between 47,000 to 41,000 years ago. Alexander Marshack, a paleolithic archeologist, studied and published on several bone carvings and cave drawings discovered in France and Germany depicting a rudimentary lunar calendar.
